OVEN DOOR SPRING FOR RANGES Filed Jan. 51 950 2 Sheets-Sheet 2 Mr *M Patented Oct. 13, 1931 UNITED STATES PATENT OFFICE WILLIAM 1). AN TRIM, OF GLOUCESTER, NEW JERSEY, ASSIGNOR TO ROBERTS & MANDER STOVE COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENN- SYLVANIA OVEN DOOR SPRING FOR RANGES Application filed January 31, 1930.

My invention relates to improvements in springs for oven doors of either gas, electric or coal ranges.

The object of my invention is to provide a spring which can be readily applied to the frame of the ran e.

A further obJect of the invention is to mount the springs on a detachable bar which can be readily secured to the frame of the range. Springs of this type are for the purpose of closing the oven door when it is partly raised or to retain the door in its full open position. This object I attain in the following manner, reference being had to the accompanying drawings, in which:

Fig. 1 is a rear view of a portion of an open frame of a gas stove, showing the oven door closed and illustrating my improved spring arrangement and the detachable supporting bar for the springs;

Fig. 2 is a sectional view on the line 2-2, Fig. 1;

Fig. 3 is a sectional view on the line 33, Fig. 1;

Fig. 4 is a side view of the detachable bar and the springs mounted thereon;

Fig. 5 is a plan view of the detachable bar with the springs removed;

Fig, 6 is a perspective view of the detachable bar; 1

Fig. 7 is a rear view similar to a portion of Fig. 1, showing the door in the open position; and

Fig. 8 is a view illustrating a modification of the invention.

1 is the frame of the oven and broiler portion of a gas range in the present instance. The lower opening 2 is the broiler opening, and the upper opening 3 is the oven opening, but these parts may be reversed without departing from the essential features of the invention. 4. is a cross-bar which extends from one side member of the frame to the other and separates the oven opening from the broiler opening. 5 is the oven door, having Serial No. 424,955.

hinge projections. 6 of the ordinary type which rock on depressed bearings 7 of the cross-bar of the oven frame. It will be understood that Where the door is provided for the broiler as well as for the oven, the hinge construction and the spring arrangement which are described hereinafter are duplicated at the broiler opening, and where other doors are provided for the gas or other range, this spring arrangement can be used without departing from the essential features of the invention. v

Each hinge projection 6 of the door is extended as at 8 and in each of these extensions are sockets 9 for the end 10 of a coil-spring 11. One of the springs is a right-hand spring-and the other is a left-hand spring as shown in Fig. 1. Each coil-spring is mounted on a post 12 projecting from a detachable bar 13, as shown in Figs. 1 and 2. r

The posts in some instances may be made integral with the cross-bar 4a of the frame of the stove, as shown in Fig. 7. Each post 12 is slotted at 14 and the slot is offset at 15, so

that when one end 16 of the coil-spring is inserted in the slot, it will be engaged by the offset portion and held onto the post. The post is conical in shape-and the spring conforms to the shape of the post.

The outer end 10 of each spring 11 is i preferably bent as shown, so that when the door is in the open position, as in Fig. 7, the bent portion 10 will rest against the wall of the socket 9 of the hinge projectiomand the spring will press againstthe edge of the spring PIOJeCtiOIl, creating a certain amount of friction which will aid inv keeping the door in the open position until it is raised past a given point.

The detachable bar 13 is held in place at of the bar fitting against the flange 21 of the frame,'sothat when the screw bolt 17 is drawn tight, there is a snug fit between the bar and the frame.

The above arrangement takes the place of the flat spring plate heretofore used. The

Y coil-springs shown are more flexible than the fiat-springs and are not so liable to break, 1
